Yeah rolling at Japanese Midnight doesn't work for my either. Got my worst pulls at that time.
The "Silver Pot" theory i was found of didn't proof it's worth either, lately.
I start to believe there is no fool proof-illuminati-mambo-jambo theory after all (Got my last Rainbow without rolling a Silver before). At least there is no theory that proofs to be consistent.
It's just luck. Meh...I want a secret technique
GZ
You worked really hard for these Rainbows.
You fought your way through a Salt Mine full of Silverpots...
Peony is a nice Rainbow though. Good for a Crit Team and she even has defensive capabilities.
